For city use among the bikes you’re looking at, the top two would be the Royal Enfield Scram 440 and Harley-Davidson X440 T. These bikes have large, long-stroke, single-cylinder engines, which will have the edge over the smaller 350s you’re looking at. However, if most of your usage is inside the city, we’d recommend sticking with the 350cc roadsters from either Royal Enfield – Hunter/ Classic / Bullet – or Honda – in the form of its CB350 trio. These bikes will have more than enough grunt for city traffic and will also return more fuel economy. Take a test ride of these to see which one suits you best.
